High voltage safety warning
Precautionary measures
The voltages used to power this equipment
are potentially lethal. Even 110 volts can kill.
Whenever possible, the following
precautionary measures must be taken before
any work is carried out inside the equipment:
S Switch off all high-voltage power supplies.
S Check the operation of any door interlocks
and any other safety devices.
S Completely discharge all high-voltage
capacitors.
It should be noted that interlocks and safety
devices are normally located only at regular
access points, and high voltages may be
exposed during dismantling.
Never work alone on high-voltage
equipment!
First aid in the event of
electric shock
Normally, even a high voltage electric shock
will not kill instantly. The victim can still be
revived even when his breathing and
heart-beat have ceased.
Could YOU save someone’s life?
In the event of electric shock, the correct
actions, performed quickly may well save the
victim’s life. Make sure you know what to
do!
Immediate action
While shouting for help, remove the source of
power from the victim. Switch off the supply
if possible, or using a dry, non-conductive
material (rubber gloves, broom handle etc.) to
insulate yourself, separate the victim from the
source. If the voltage exceeds 1000 volts,
switch off the supply and be ready to catch
the victim. Take care- do not become a victim
yourself.
Commence first aid on the spot. Continue to
shout for assistance till someone arrives.
1 Lay the victim flat on his back and loosen
any tight clothing (collar, tie, belt etc.).
2 Open his mouth and check for and remove
any false teeth, chewing gum etc.
3 Check if the victim is breathing. If not,
check if his heart is beating. The pulse is
normally easily found in the main arteries
of the neck, either side of the throat, up
under the chin.
If his heart is beating but he is not breathing,
commence artificial respiration. If the
victim’s heart is not beating, commence
external cardiac massage (ECM). Continue to
shout for assistance till someone arrives.
External cardiac massage
1 Kneel beside the victim. Place the heel of
one hand in the centre of his chest, at a
position half way between the notch
between the collar-bones at the top of his
chest, and the dip i n the breast-bone at the
base of his rib cage. Place the other hand
on top of the first.
2 Keeping the arms straight and using your
entire weight, press down rapidly so that
the breast bone is depressed four- five cm,
then release the pressure. Repeat
rhythmically at a rate of one cycle per
second. This will be hard work, but keep
going. His life depends on YOU. Do not
worry about breaking his ribs - these will
heal if he survives.
Simrad SP270
VI
851-160570 / B
Artificial respiration
1 Kneel besides the victim’s head. Place one
hand under his neck and lift, allowing his
head to fall back. This will lift his tongue
and open the air passage in his throat.
2 Place the palm of the hand on his forehead
to maintain the ”chin-up” position.
3 Using the index finger and thumb of the
same hand, pinch the victim’s nostrils
closed. Open his mouth.
4 Take a deep breath and cover his mouth
with yours. Blow steadily into his lungs to
expand his chest. Remove your mouth
from his to allow the air t o escape from his
chest. You should be able to see his chest
deflate.
5 Repeat the ”inflation-deflation” cycle at a
rate of about 12 cycles per minute till the
victim begins to breath normally again.
Combining ECM and artificial
respiration
If you are alone, perform one cycle of
artificial respiration for every five cycles of
ECM. This will be hard work, but keep going.
His life depends on you!
If there are other people available to help, one
should perform the ECM while one performs
the artificial respiration for every five cycles
of ECM. It will be much more efficient with
two people.
Once the victim’s heart is beating and he is
breathing, roll him onto his side and support
him in that position. As consciousness returns
he may vomit, and this will allow any liquid
to drain out of his mouth.
Remove the victim to a hospital as soon as
possible, but do not interrupt the artificial
respiration and ECM cycles till his heart beat
and breathing returns.
If started quickly and performed correctly, the
resuscitation methods described will keep a
sufficient volume of oxygenated blood
flowing trough the victims body to allow full
recovery.
Proficiency in the resuscitation methods can
only be achieved trough training. All
personnel concerned should attend courses on
a regular basis. Remember, someone’s life
could depend on you.
Do you know what to do?

Installation document
This installation manual will act as an installation document for
later updating and service on the sonar, and must therefore be
stored on board the vessel into which the equipment is to be
installed.
To ensure the best possible result of the installation, it is
important that each procedure is carefully followed. Each listed
procedure comprises squares for ticking off while proceeding in
the procedure. In addition to be a sign that the procedure is
followed, this will also be a good guidance for the installer.
Note that the installer becomes fully responsible for the
equipment during the installation, and that the guarantee only is
covered when the installation is made in full accordance with
this installation manual.
Overview
General
The Simrad SP 270 Sonar system is delivered without a dome
system. The Hull Unit uses a Simrad SQ4 installation trunk. The
SP 270 can therefore easily be mounted in an old SQ4 or SR
240 trunk. Note that the trunk is not included in the standard
delivery. This trunk may be made by the shipyard, or be
delivered from Simrad as an option (see chapter 2.3 “Options”).
The optional trunk which is approved by Det norske Veritas
(DnV) also includes a blind cover and a gasket.
The drawings of the trunk and blind cover are included in
section “Drawings”.

Supply conditions
Purpose
The following supply conditions are applicable to standard
Simrad SP270 deliveries and associated optional equipment.
Equipment responsibility
The shipyard performing the installation and/or dealer becomes
fully responsible for the equipment upon receipt unless
otherwise stated in the contract.
The duration of responsibility includes:
• The period of time the equipment is stored locally before
installation.
• During the entire installation process.
• While commissioning the equipment.
• The period of time between commissioning and the final
acceptance of the equipment by the end user (normally the
owner of the vessel which the equipment has been installed).
The Simrad SP270 system guarantee period (as specified in the
contract) begins when the acceptance documents have been
signed unless other arrangements have been made in the
contract.
Receipt, unpacking and storage
Upon accepting shipment of the equipment, the shipyard and/or
the dealer should ensure that the delivery is complete and
inspect each shipping container for evidence of physical
damage. If this inspection reveals any indication of crushing,
dropping, immersion in water or any other form of damage, the
recipient should request that a representative from the company
used to transport the equipment be present during unpacking.
All equipment should be inspected for physical damage, i.e.
broken controls and indicators, dents, scratches etc. during
unpacking.
If any damage to the equipment is discovered, the recipient
should notify both the transportation company and Simrad so
that Simrad can arrange for replacement or repair of the
damaged equipment.
Once unpacked, the equipment must be stored in a controlled
environment with an atmosphere free of corrosive agents,
excessive humidity or temperature extremes. The equipment
must be covered to protect it from dust and other forms of
contamination when stored.
Introduction

851-160571 / B
General safety rules
The system operates on 115 and/or 230 / 380 / 440 Vac, 50/60
Hz.
Warning This voltage can be lethal.
The following safety precautions must be followed at all times
during installation and maintenance work:
• Always switch off all power before installation or
maintenance. Use the main circuit breaker, and label the
breaker with a warning sign that informs others that
maintenance or installation work is being carried out on the
system.
• Read and understand the first aid instructions for electric
shock.
• For safety reasons during troubleshooting on the equipment
with power ON, two persons should always be present.
• Whenever maintenance is carried out, it is essential that a
first aid kit is available, and that the maintenance personnel
are familiar with the first aid instructions for electrical shock.
• The various parts of the system are heavy. Make sure that the
appropriate tools and certified lifting equipment are
available, and that the personnel are trained in installation
and maintenance work.

851-160571 / B
Installation requirements
Responsibility and approval
The Simrad SP270’s Hull Unit sleeve has been approved by Det
Norske Veritas (DNV) Classification society.
Individual Hull Unit installations must be approved on a
case-by-case basis with regard to the vessel’s national registry
and corresponding maritime authority. The shipowner and
shipyard performing the installation are responsible for
obtaining installation approval.
Supply power
The supply voltage to the equipment is to be kept within ±10%
of the installation’s nominal voltage. Maximum transient
voltage variations on the main switchboard’s bus-bars are not to
exceed -15% to +20% of the nominal voltage (except under
fault conditions).
Simrad strongly recommends that the SP270 sonar be powered
using an Uninterruptible Power Supply (UPS). The UPS should
have the capacity to independently maintain power to the sonar
for a minimum of 10 minutes. This ensures that the system can
be switched off in a controlled manner in the event of a power
failure.
Environmental requirements
Temperature and humidity
All equipment, unless otherwise specified, must be protected
from temperature extremes and excessive humidity.
Compass deviation
Once the installation is complete, the vessel must be swung with
the sonar in both the operative and inoperative modes. The
shipowner and captain are responsible for updating the deviation
table accordingly with regard to the vessel’s national registry
and corresponding maritime authority.
Noise sources
The vessel’s hull, rudder(s) and propeller(s) should be
thoroughly inspected in dry dock prior to installation.
Roughness below the water-line deformities in the shell plating
and protruding obstacles can create underwater noise. These
sources of turbulence must be smoothed or removed as best as
possible. It is especially important that the propeller(s) is not
pitted or damaged.
Introduction
9
851-160571 / B
Dry docking
Make sure that ample clearance under the sonar trunk and/or
protection blister is provided when dry docking the vessel.
Avoid locating supporting blocks or structures in the vicinity of
this equipment.
Note The location of the sonar trunk and/or protection blister must be
noted on the vessel’s docking plan for future reference.
Wiring
The cable from the wheelhouse to the sonar room must be
supported and protected along its entire length using conduits
and/or cable trays. Note that the cable must not be installed in
the vicinity of high-power supplies and cables, antenna cables or
other possible sources of interferences.

851-160571 / B
Equipment handling
Introduction
This chapter describes how to transport, pack and unpack, clean,
preserve and store electronic, electro-mechanical and
mechanical units supplied by Simrad AS.
The units may be supplied as spare parts, or as parts of a
delivery.
Transportation
General specifications
Unless otherwise stated in the accompanying documentation,
electronic, electro-mechanical and mechanical units supplied by
Simrad can be transported using all methods approved for
delicate equipment; e.g. by road, rail, air or sea. The units are to
be transported in accordance with general or specific
instructions for the appropriate unit(s), using pallets, transport
cases, or carton boxes as appropriate.
Note Special local restrictions concerning air transportation may be
applied to units containing certain types of batteries. The units
should be checked and the regulations investigated by the
packer/shipper before the unit is dispatched.
Local transportation
All local transportation must be carried out according to the
same specifications as for the initial delivery. In general, all
units must be handled with care. The carton or case containing
the equipment must be kept dry at all times, and must be
sheltered from the weather. It must not be subjected to shocks,
excessive vibration or other rough handling.
The carton or case will normally be marked with text or symbols
indicating which way up it is t o be placed. Follow any
instructions given and ensure the case is always placed with its
“top” uppermost.
The carton or case must not be used for any purpose for which it
was not intended (e.g. step, table, etc.), and in the absence of
other information, no other cartons or cases must be stacked on
top of it.
Introduction
11
851-160571 / B
Lifting
A heavy crate will normally be marked with its weight, and the
weights of other cartons or crates will normally be entered on
the packing list.
• Always check the weight of a crate before attempting to lift
it.
• Always use lifting apparatus that is certified for the load.
Heavy units may be equipped with lifting lugs for transportation
by crane within the workshop or installation area. Before a crane
is used, check:
• The applicable weight certificate for the crane.
• The security of the lifting lugs.
Ensure that all available lifting lugs are used. Ensure the unit
remains under control during the operation to avoid damage to
the unit, equipment or personnel.
Heavy units may be transported using a fork-lift t ruck. Special
attention must then be paid to the position of the unit’s centre of
gravity. The units must be properly secured to the truck.
Initial preservation
Introduction
When a system, a unit or a spare part has been delivered to the
customer, it may be subject to long-time storage prior to
installation and use. During this storage period, certain
specifications must be met.
The equipment must be preserved and stored in such a way that
it does not constitute any danger to health, environment or
personal injury.
Specific specifications are presented below.
→ For further information about storage, refer to page 15.
→ For further information about re-packing, refer to page 18.
→ For further information about temperature protection, refer to
page 19.
Original packing crate
1 The equipment must be stored in its original transportation
crate.
2 Ensure that the units are clearly separated in the shelves
and that each unit is easily identifiable.
3 The crate must not be used for any purpose for which it
was not intended (eg. work platform etc.).
Simrad SP270
12
851-160571 / B
4 The crates must not be placed on top of each other, unless
specific markings permit this.
5 The crates must not be placed directly on a dirt floor.
6 Do not open the crate for inspection unless special
circumstances permit so.
- “Special circumstances” may be suspected damage to
the crate and its content, or inspections by civil
authorities.
- If any units are damaged, prepare an inspection report
stating the condition of the unit and actions taken.
Describe the damage and collect photographic evidence
if possible. Re-preserve the equipment.
- If the units are not damaged, check the humidity
absorbing material. If required, dry or replace the bags,
then repack the unit(s) according to the packing
instructions.
7 If the crate has been opened, make sure that is it closed
and sealed after the inspection.
- Use the original packing material as far as possible.
→ Refer to the information on page 18.
Ambient temperature and humidity
1 The storage room/area must be dry, with a non condensing
atmosphere. It must be free from corrosive agents.
2 The storage area’s mean temperature must not be lower
than -30°C, and not warmer than +70°C.
- If other limitations apply, the crates will be marked
accordingly.
Note Transducers must not be stored in temperatures below -20°C.
3 The crate must not be exposed to moisture from fluid
leakages.
4 The crate must not be exposed to direct sunlight or
excessive warmth from heaters.
Shock and vibration
1 The crate must not be subjected to excessive shock and
vibration.
ESD precautions
→ Refer to the information on page 18.
Introduction
13
851-160571 / B
Batteries
If the unit contains normal batteries, these may have been
disconnected/isolated before the unit was packed. These must
only be reconnected before the installation starts. Units
containing batteries are marked.
Caution Units containing lithium or alkaline batteries must be
handled separately and with care. Such units are
marked accordingly. Do not attempt to recharge such
batteries, open them or dispose of them by
incineration. Refer to the applicable product data
sheets.
Inspection and unpacking
Inspection
An inspection must be carried out immediately after the unit(s)
have arrived at their destination.
• Check all wooden or cardboard boxes, plastic bags and
pallets for physical damage. Look for signs of dropping,
immersion in water or other mishandling.
• If damage is detected externally, you will have to open the
packaging to check the contents.
- Request a representative of the carrier to be present while
the carton is opened, so any transportation damage can be
identified.
• If any units are damaged, prepare an inspection report stating
the condition of the unit and actions taken. Describe the
damage and collect photographic evidence if possible. Send
the inspection report to Simrad as soon as possible.
• If the units are not damaged, check the humidity absorbing
material. If required, dry or replace the bags, then repack the
unit(s) according to the packing instructions.
General unpacking procedure
Normal precautions for the handling, transportation and storage
of fragile electronic equipment must be undertaken.
Note If the unit is not to be prepared for immediate use, you may
consider storing it unopened in its original packing material.
However, it may be useful to open the case to check its contents
for damage and retrieve any accompanying documentation.
• Check the carton before opening it to ensure it shows no
signs of dropping, immersion in water or other mishandling.
- If the carton shows signs of such damage, refer to the
paragraph covering Inspection on receipt.
Simrad SP270
14
851-160571 / B
• Place the carton on a stable work bench or on the floor with
the top of the carton uppermost.
• In the absence of other instructions, always open the top of
the carton first. The contents will normally have been
lowered into the carton from above, so this will usually be
the easiest route to follow.
- Care must be used when opening the carton to ensure the
contents are not damaged.
Caution Do not use a knife to open cardboard cartons - the
contents may lie close to the surface, and may be
damaged by the blade.
• If the carton has been closed using staples, remove the staples
from the carton as you open it. This will reduce the
possibilities of scratch injury to yourself and damage to the
contents.
• If a wooden crate has been closed using screws, always
remove them using a screw-driver. Do not attempt to prise
the lid off with a crow-bar or similar.
• Once the carton is open, carefully remove all loose packing
and insulation material. Check for manuals and other
documents that may have been added to the carton during
packing, and put these to one side. Check also for special
tools, door keys etc.
Electronic and electro-mechanical units
Caution BewareofthedangersofElectro-StaticDischarge
(ESD) both to yourself and to the equipment, when
handling electronic units and components. Refer to the
precautions starting on page 18.
Electronic and electro-mechanical units will normally be
wrapped in a clear plastic bag. Lift the unit, in its bag, out of the
carton and place it in a stable position on the floor/work bench.
Inspect the unit for damage before opening the plastic bag.
Note Cables must never be used as carrying handles or lifting points.
Note Do not break the seal to open a circuit board package before the
board is to be used. If the board package is returned to the
manufacturers with the seal broken, the contents will be
assumed to have been used and the customer will be billed
accordingly.
Assuming all is well, open the bag and remove the unit.
Open the unit and check inside. Remove any packing and
desiccant material that may be inside.

Mechanical units
Mechanical units may be heavy. Using a suitably certified lifting
apparatus, lift the unit out of the crate and place it in a stable
position on the floor/work bench.
Inspect the unit for damage and remove any packing material
that may be inside the unit.
Transducers
Transducers may be supplied mounted to a hull unit (if any), or
packed separately. Crates are normally identified by the order
number and the serial number.
The transducer face must be protected by a rigid, padded cover
(e.g. a wooden box lined with foam rubber) all the time it is
exposed to the risk of physical damage.
Note Once the units are unpacked, great care must be taken to ensure
that transducers and cabling are not exposed to any mechanical
stress.
Re-packing
If the unit is not to be installed immediately, re-pack it in its
original packing material to prevent damage in the intervening
period.
→ Refer to the information on page 18.
Storage
Pre-installation storage
The equipment should be stored in its original transportation
crate until ready for installation. The crate must not be used for
any purpose for which it was not intended (eg. work platform
etc.).
Once unpacked, the equipment must be kept in a dry, non
condensing atmosphere, free from corrosive agents and isolated
from sources of vibration.
Note Do not break the seal to open a circuit board package before the
board is to be used. If the board package is returned to the
manufacturers with the seal broken, the contents will be
assumed to have been used and the customer will be billed
accordingly.
The unit must be installed in its intended operating position as
soon as possible after unpacking.

If the unit contains normal batteries, these may have been
disconnected/isolated before the unit was packed. These must
then be reconnected during the installation procedure. Units
containing batteries are marked.
Caution Units containing lithium or alkaline batteries must be
handled separately and with care. Such units are
marked accordingly. Do not attempt to recharge such
batteries, open them or dispose of them by
incineration. Refer to the applicable product data
sheets.
After use storage
Introduction
If a unit is removed from its operating location and placed into
storage, it must be properly cleaned and prepared before
packing.
Cleaning cabinets
If the unit may have been exposed to salt atmosphere while it
was in use, it must be thoroughly cleaned both internally and
externally to prevent corrosion.
• Wipe the cabinet externally using a damp cloth and a little
detergent. Do not use excessive amounts of water as the unit
may not be water tight. On completion, dry t he unit
thoroughly.
• All surfaces must be inspected for signs of corrosion, eg.
flaking/bubbling paint, stains etc. Damaged or suspect areas
must be cleaned, prepared and preserved using the correct
preservation mediums for the unit. The mediums to be used
will usually be defined in the units’ maintenance manual.
• Open the unit, and using a vacuum cleaner, remove all dust
etc. from the unit. Great care must be taken to ensure the
circuit boards and modules are not damaged in the process.
Mechanical units
If the mechanical unit may have been exposed to a salt
atmosphere while it was in use, it must be thoroughly cleaned
both internally and externally to prevent corrosion.
• If the construction materials and type of unit permits, wash
the unit using a high-pressure hose and copious amounts of
fresh water.
Examples:
- The lower parts of hull units (outside the hull)
- Subsea units
